I have a Rampage Formula with a Q9450 and 4X1GB of Corsair Dominator 1066 ram. I tested each module in each DIMM slot and it boots up fine, tried 2 sticks in all slots and it works fine. But with all four slots populated, it won't POST. I get a DET DRAM error on the LCD poster. Any help will be appreciated.
make sure the mb bios is up to date. if it is..run cpu-z and look at the ram voltage and timing if it set to xmp profile and is 1.65 in voltage under the spd tab info you may have to bump the dram and chipset voltage for all 4 dimms to post.
